5.2.4 The scope supported by JP1
When you are using JP1 in a cluster system, JP1 only supports its own operations. Control over the logical host environment (shared disk and logical IP address) depends on the control over the clustering software.
If the prerequisites for a logical or physical host environment described above are not satisfied or if there is a problem in controlling the logical host environment, JP1 does not address the problems that might occur with JP1 operations. In such a case, the clustering software or OS controlling the logical host environment must address the problem.
